Abstract (en)

An electricity storage device, an electricity storage system and a power supply system capable of setting a full charge capacity corresponding to an actual full charge capacity are developed. The electricity storage device includes a battery part, and a control part that controls charge and discharge of the battery part. The battery part is capable of discharging from a full charge capacity to a preset set capacity. The control part is capable of executing a full charge capacity correction mode. The full charge capacity correction mode executes: a remaining capacity calculation operation in which, when the battery part discharges from the full charge capacity to the set capacity, a remaining capacity corresponding to a first voltage of the battery part in a state of having discharged to the set capacity is calculated based on a preset correlation between a voltage and a battery capacity of the battery part, and a consumed capacity calculation operation in which a consumed capacity consumed from the full charge capacity to the set capacity is calculated by calculating a current amount of the battery part during a time period from the full charge capacity to the set capacity. A sum of the remaining capacity and the consumed capacity is set as a full charge capacity.
